Turbo levo 29ht speed sensor?

[Kimmoi]

How does it works? I assume that sensor is inside the chainstay, but where sensor reads data; there is nothing on the wheel? Is there hidden magnet or something like that?
And how about if you put new wheels on your bike, like 27,5 instead 29? Does the sensor work?

The magnet is mounted on the rear brake disc.
Sensor is neatly hidden there.
So no problem changing wheels as long as you swap the magnet/disc too.

Thanks!

I assume you would also have to update the wheel size in the Mission Control app or BLevo e.t.c if you changed from the stock size of 27.5 diameter wheels...(anyone ?)

I think 3” 27.5 has about same outer diameter as 2.3” 29?
Even close, i think. Depends tire profile etc?
